FDA Study Reports Chemical Sunscreens Enter Bloodstream in One-Day

In a recent report and study by the FDA, it appears they are on a path to ban all chemical sunscreen ingredients used in most sunscreens on the market. Keys Solar Rx is a clear physical sunscreen using zinc oxide.

The four chemicals studied — avobenzone, oxybenzone, ecamsule and octocrylene — are part of a dozen that the FDA recently said needed to be researched by manufacturers before they could be considered “generally regarded as safe and effective.”

Today, researchers at the FDA revealed the results of a small clinical trial designed to test how four of the most common sun-filtering molecules on the market behave after they’ve been sprayed on and rubbed in. The results, published in the journal JAMA, show that contrary to what sunscreen manufacturers have been saying, UV-blocking chemicals do seep into circulation. Now, don’t panic and toss your tubes. There’s no evidence yet that they’re doing anything harmful inside the body. But the revelation will have serious impacts on sunscreen manufacturers going forward, and may change what options you’ll find on drugstore shelves before the year is out.

“Everyone had always thought that because these are intended to work on the surface of the skin that they wouldn’t be absorbed, but they are,” says Theresa Michele, director of the FDA’s division of nonprescription drug products, and coauthor on the FDA-funded study. Her team found that it took only a few hours after the application of sunscreen for the photoprotective chemicals to infiltrate the bloodstream and shoot up to concentrations above the FDA’s toxicology threshold that triggers further safety testing.
